    You add everything to the Panel p but you never add that panel to the applet. What you probably want is to add everything to the applet. An applet is a special kind of panel so you can just change "p" to "this" everywhere in init and remove the declaration of p at the top.

    I am trying to port a Java application from the PC to the Mac. I am using XCode and the program compiles, but it does not run.
    When I try to run the ...app, I get the message that the main class is not specified, etc.
    When I try to run the ...jar, I do not get the message that the main class is not specified, but I do get the message that there is no Manifest section for bouncycastle, etc.
    Here are the detailed messages I get in the Console when I try to run the program:

    I do specify the main class in both, the Manifest file and the Info.plist file, in the correct way, "package.MainClass". Is there another place where I need to specify it?
    Why do I need org/bouncycastle/asn1/DEREnumerated.class, and how would I have to specify it in Manifest?
    I also posted these questions at Mac Programming at forums.macrumors.com and at Xcode-users Mailing List at lists.apple.com/mailman/listinfo, but I did not get any answer.
    Please help! Thanks!

    There was something wrong with my Info.plist file.
    So, here is my corrected Info.plist file:
    <?xml version="1.0" encoding="UTF-8"?>

    However, I still cannot run the AnanyaCurves.app file. When I double-click on it, I get the following message in the Console:

Isn't this outdated? Shouldn't it look for the Info.plist file? I do not have a MRJApp.properties file.
    Also, in the Run menu of my XCode project, Go, Run, and Debug are disabled, but perhaps this has to do with not being able to run the AnanyaCurves.app file.
    Thanks for your time! I really appreciate any help you can give me!

  • Tcode opens selection screen, but does not executes the program

    Hi!
    tcode opens selection screen of a custom program, but it seems that it does not executes the program itself.
    Sounds strange, but how to explain this if I can run a program manually with no problem and it displays result screen, but when I try to run the program with tcode - it opens selection screen but program quits before displaying result screen. I was putting a breakpoint at the begining of the program - it does not triggers debuger when running a tcode (it triggers debugger if to run program manually).... any ideas?
    Help will be appreciated,
    Mindaugas

    Are you using this???
          SET PARAMETER ID '80B' FIELD T_TABLE-OPBEL.
          CALL TRANSACTION 'FPE3' AND SKIP FIRST SCREEN.
    That way it should work....
    Greetings,
    Blag.

  • This program is well compiled but does not work.

    I would like to know why this program does not work properly:
    the idea is :
    1. the user introduces a text as a string
    2.the progam creates a file (with a FileOutputStream)
    3. then this file is encripted according to DES (using JCE, cipheroutputStream)
    4.the new filw is an encripte file, whose content is introduced in a string (with a FileInputStream)
    (gives no probles of compilation!!)
    (don know why it does not work)

    If you don't require your code to run as an applet, you will probably get more mileage from refactoring it to run as an application.
    As sudha_mp implied, an unsigned applet will fail on the line
    FileInputStream fe=new FileInputStream("c:/javasoft/t.txt");
    due to security restrictions. (Which, incidentally, are there for a very good reason)

  • Compiles Fine, but Does Not Execute

    I'm using jdk 1.3.1 since that is what my school uses.
    This program is really simple, the user is supposed to pick a type of variable then put data that is valid for that data type, and if they're wrong the catch numberformatexception would tell them. I've looked at the code for awhile, its not the best but I dont see why it doesn't run maybe someone could scan through the code and see if something stands out. I know its annoying when someone posts their entire programs code but since I have no idea where my problem is help would be most appreciated.

    I am using version 1.4, and your code executes on my
    machine.
    What happens when you try it on your machine? An
    exception?
    Nothing? You might get rid of the "throws
    IOException"
    from main's signature and see if that helps... I seem
    to
    remember that the exception list was part of the
    signature,
    though I might be in error there.It isn't. There is nothing wrong with have exception specification on the main method.

  • Applet Servlet communication compiles but does not communicate

    Hi,
    I have a applet which has a button named A. By clicking the button, the applet passes the letter A to the servlet. The servlet in turn accesses an Oracle database and retrieves the name corresponding to letter A from a table (name is Andy in the present case). The servlet interacts with the databse via a simple stored procedure and uses its output parameter to display the name Andy back in the applet.
    Both the applet and servlet codes have compiled fine(servlet code compiled with -classpath option to servlet jar using a TOMCAT). However, on clicking button A in the applet, I do not get the name Andy.
    Any help/suggestion in resolution of this is highly appreciated. Thanks in advance.

  • Deferred Event Subscription Processed but does not execute PL/SQL Rule Func

    Greetings all,
    I am creating a simple Business Event Subscription w/ a PL/SQL Rule Function in my 11.5.10.CU2/10gR2 E-Business Suite environment. My custom code simply inserts a record into a custom table. When I setup the Subscription to run synchronously (i.e. Phase < 100), the PL/SQL function executes and a record is inserted into my custom table. When I setup the Subscription to run in a deferred manner (i.e. Phase Code >= 100), no record is inserted into my custom table.
    The Service Component "Workflow Deferred Agent Listener" is running. A close inspection of the WF_DEFERRED queue tables reveal that the message/entry is being processed (I can see the status change from READY to PROCESSED), but the PL/SQL function is never executed.
    I would prefer to setup the Subscription to be deferred in order not to degrade performance of the user's session that triggers the business process. What am I missing?
    Thanks,
    Jeff

    Jeff,
    If you are using global variables in your custom code to insert, you may want to stop and start the WF agent listener and then try firing the event.
    Thanks

  • PS3 droplet called from command line in XP reads in files but does not execute action

    Hello.
    I am a researcher interested in anxiety disorders in young children. As part of a functional magnetic resonace brain imaging study we need to compare children's responses to familiar and unfamiliar faces. The latter are no problem, but for the former we need to take pictures of the children's mothers and process them "on the fly" so that they can be incorporated into stimulus sets presented in the MRI machine (otherwise known as the "magnet").
    For presentation in the magnet, the images have to be in a particular format. I have created an action that produces the appropriate format, and a PS3 droplet that behaves appropriately (outputs correctly modified files to the stated address) when a Windows XP (SP3) folder is dropped on it.
    However, I need to automate the procedure further because it will be executed by individuals with little or no understanding of PS etc.
    It occurred to me that I could call my droplet from the XP command line with the folder containing the relevant files as an argument (and then I would be able to incorporate this function into an overall control program).
    However, I have found that this approach loads the relevant files into CS3, but that the actions don't run.
    I would very much appreciate any help with this problem.
    Thank you.
    Adrian Angold.

    A command line script might work, but would lack a user interface. Error
    processing and logging capabilities would also be limited.
    I would consider writing a small application in a language such as Visual
    Basic or C# that uses Photoshop's automation interface. The automation SDK
    is provided on the Photoshop DvD.

  • Moved 8.1 - Nodemanager starts but does not work... SSL problem..

    Hello!
    We moved our weblogic 8.1 installation to a new production machine (which used to be very easy with weblogic 5.1) but of course, it didn't work because of the SSL demo certificates which were tied to the old server name. It dumped the following line on the log and refused to work:
    ...Certificate chain received from localhost - 127.0.0.1 failed hostname verification check
    We changed our demo certificates as stated in the documentation (certgen, keytool...) and now it starts ok but does not work either. Now we are seeing the following expection on the logs:
